Please explain structure and functions of the pineal gland with diagram.
You can refer to answers given by your friends. They have answered well. However, I am providing you a simplified answer.
- Location − Dorsal side of forebrain. It is very small in size 5-8mm
- Secretes melatonin that regulates 24-hour (diurnal) rhythm of the body such as sleep-wake cycle, body temperature, etc.
- Melatonin also regulates metabolism, pigmentation, and menstrual cycle.
@ Others : Good work. Keep posting!!
The pineal gland (also called the pineal body, epiphysis cerebri, epiphysis, conarium or the "third eye") is a small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns and seasonal functions. Its shape resembles a tiny pine cone (hence its name), and it is located near the centre of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join.
FUNCTIONS: The pineal gland is involved in several functions of the body including:
- Secretion of the Hormone Melatonin
- Regulation of Endocrine Functions
- Conversion of Nervous System Signals to Endocrine Signals
- Causes Feeling of Sleepiness
- Influences Sexual Development
hope it helped ,,, best of luck:)
